A teacher cover letter is read by someone who has sat through hundreds of them and can spot a generic one by the second line. The good news is that schools want something specific and fairly predictable: proof that you can run a classroom, that you fit this phase and subject, and that you understand where you are applying.
Who actually reads your letter
Before you write a word, work out who will open it. In a small primary school, it is often the head teacher, reading applications at the kitchen table on a Sunday evening. In a large secondary school, a head of department may shortlist and then pass a handful of letters to a panel that includes a deputy head and sometimes a governor. In a school group or a district, an HR team may screen first for eligibility before anyone with classroom experience looks at your content.
Each reader wants something slightly different. A head teacher is asking whether you will fit the staffroom and whether parents will trust you. A head of department wants to know you can teach the specification and pull your weight on shared planning. An HR screener is checking that you hold the right qualification, that your dates make sense and that you answered the job advert.
Write for the person who makes the decision, but make the screener's job easy too. Put your qualification, your subject and the phase you teach in the first paragraph, so nobody has to dig for them.
Open with subject and phase fit
The most common weak opening in a cover letter for a teaching position is a sentence about passion for education. Every applicant has it, so it carries no information. Open instead with what you teach, at what level, and why this post matches it.
Compare these two openings:
- "I am writing to apply for the teaching position advertised on your website. I have always been passionate about helping young people learn."
- "I am a qualified secondary science teacher with four years of experience teaching biology up to A level, and I am applying for the biology post at Riverside Academy because your sixth form is growing and I have built a Year 12 course from scratch before."
The second version tells the reader your subject, your phase, your level of experience and a concrete reason you chose them. If you need more ideas for that first line, the examples in our guide to cover letter examples by industry show how the same principle works in other fields.
Be honest about range. If you are a primary teacher applying for a Year 6 role, say whether you have taught upper key stage 2 before. If you are a secondary teacher who can cover a second subject, name it and say at what level, rather than claiming you can teach anything.
The one classroom example that proves impact
This is the paragraph that gets you shortlisted. Pick one class, one problem and one change you made, then describe what moved. Keep it to four or five sentences.
A strong example has a starting point, an action and an observable result. The result does not need to be a percentage. It can be that a reluctant group started handing in homework, that a pupil who had stopped speaking in class read aloud in an assembly, or that a department adopted your approach.
Here is an illustrative paragraph from an invented applicant, Sarah, applying to a primary school:
Last year my Year 4 class included a group of six pupils who were reading well below the expected level and avoiding books altogether. I set up a fifteen-minute daily reading slot built around short graphic novels they chose themselves, and I paired each of them with a confident Year 6 reader once a week. By the spring term, all six were taking books home voluntarily, and two of them asked to join the school library club. The approach is now used across lower key stage 2.
Notice what she does not do. She does not claim to have transformed the school or invent a statistic. She describes a specific group, a specific change and a believable outcome, and she hands the panel an obvious question for interview.
Show you know this school
Schools can tell a mail-merged letter from one written for them. One or two sentences of genuine school-specific detail are enough, and they should connect to your own work rather than flatter the school.
Good sources include the school website, its latest inspection report, its newsletters and any information pack that came with the advert. If the school runs a strong outdoor learning programme and you have led forest school sessions, say so. If it has recently opened a specialist resource base and you have experience with pupils who have additional needs, link the two.
If you visited the school or taught an observed lesson during a previous round, mention it briefly. A line such as "When I visited in March, I was struck by how the Year 7 tutor groups run their morning reading time, and I would be glad to contribute to it" shows genuine interest and reminds the reader that they have already met you.
Safeguarding, behaviour and the rest of the job
Safeguarding is part of every teaching role, and the person reading your letter will notice whether you mention it. One sentence is enough. Something like "I take safeguarding seriously, keep my training up to date and know how to record and pass on a concern" signals that you understand the responsibility without turning the letter into a policy document.
Behaviour management deserves a line too, ideally folded into your classroom example rather than stated in the abstract. Then add anything else the advert asks for: a club you could run, experience with a particular exam board, pastoral work as a form tutor, or a willingness to contribute to trips. Match these to the person specification, point by point, and skip anything it does not mention.
Keep the whole letter to one page. Four or five short paragraphs is a sensible target, and our guide to writing a teacher CV covers the details that belong on the CV instead, such as full training history and every post you have held.
A simple structure you can reuse
If you are applying to several schools, a repeatable structure saves time without making every letter identical:
- Opening: your qualification, subject, phase and the specific post.
- Classroom example: one class, one change, one outcome.
- School fit: one or two details about this school linked to your experience.
- Wider contribution: safeguarding in one line, plus extracurricular or pastoral work the advert mentions.
- Close: availability for interview or an observed lesson, and a polite sign-off.
Only paragraphs one, three and five need heavy rewriting for each school. Your classroom example can stay largely the same, although you might swap it for a different one if the post is in another phase.
If you are leaving teaching for another field, the letter changes completely, and that is a different conversation. For a school application, keep the focus on pupils and learning throughout.
Before you send it
Read the letter once as the head teacher would, then once as the HR screener. Check that your qualification and subject appear in the first paragraph, that you named the school and the post correctly, and that the classroom example reads as a real story rather than a slogan.
Then make sure your CV tells the same story. If your LinkedIn profile is up to date, Postulit can turn it into a clean CV in a few minutes, so the dates, roles and responsibilities match what your letter claims. Send both as PDFs, name the files with your surname and the post, and keep a copy of every letter you send so you can prepare for interview from it.
